Title: Cdma mobile communication system and transmitter receiver
Inventor: SUNAGA TERUKI
IPC: H04B1/707
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To prevent transmit signals from other base stations from being superposed as noise components by transmitting pilot channel signals of respective base stations at respectively shifted time intervals. SOLUTION: A pilot data generation part 1, an information modulation part 2, and a spread spectrum modulation part 3 of a pilot channel transmission part 40 of a base station transmit data of a pilot channel by one cycle of a spread signal at every specific time interval with an instruction of a pilot transmission timing generation part 15. Here, the pilot channel transmission start time of each base station is shifted by its characteristic time offset and plural base stations never transmit pilot signals at the same time. An inverse spread part of a pilot channel reception part of each mobile receiver inversely spreads a signal of the pilot channel only with transmission timing from the base station that it belongs to. Further, none of other base station performs transmission at the point of time.  Consequently, transmit signals from other base stations are not superposed as noise components and the S/N does not deteriorate.

Abstract: PURPOSE:To attain stable special reproduction of a constant linear velocity disk by replacing either a reproduction synchronizing or a reference synchronizing signal inputted to a phase comparator circuit during the production period of a gate pulse and inputting the same two signals. CONSTITUTION:At the special reproduction of the constant linear velocity disk, when a jump trigger signal is inputted to a gate generating circuit 11, it is latched by a DFF 12 and a switch 5 is changed over. The switch 5 is turned to the position of the reference synchronizing signal when the switching signal is at an H level and the two same signal are given to the phase comparator 7 and no time base error signal is caused even if there is any discontinuity in the reference synchronizing signal and the recovered synchronizing signal. When the signal goes to an L level, the switch 5 is turned to the position of the recovered synchronizing signal, but the phase shift of the reference synchronizing signal is finished, no time base error signal is caused and the lock state of the servo system is maintained. Thus, the special reproduction of the constant linear velocity disk is made stable.

Title: Rubble foundation mound formation work
Inventor: TANAKA KAZUMASA
IPC: E02B3/12
Filed: 1981-06-19
Abstract: PURPOSE:To obtain a rubble-mound having a high flatness without the needs for leveling work by a method in which baggy mat provided to a framework is covered on a rubble-mound, rubber is charged into the space of the baggy mat, and then cement mortar is placed. CONSTITUTION:A rope 12 is sent out of a base ship 4, a framework 6 is brought down to near the upside of a rubble foundation mount 3, a rope 11 is wound up to spread a mat 5, and the framework 6 is further settled to cover the mount 3 with the mat 5. Since the lower side sheet 5b of the mat 5 has a larger area than that of the upside sheet 5a, the mat 5 can well fit the uneven surface of the rubble-mound 3 to closely cover it. Then, cement mortar is injected through a tube from the base ship 14 into the space S of the mat 5. Since the upward expansion of the upside sheet 5b is prevented by the framework 6, the mount whose upper end face is always flattened can be formed regardless of the shape of the upside of the mound 3.

Abstract: PURPOSE: To reduce the rising and reducing gradients of temperature and humidity and increase the efficiency of air conditioning equipment by controlling the operation of an air conditioning system so that the temperature and humidity in a room during an air conditioned time band may gradually rise or fall as time passes.  
     CONSTITUTION: The sequential change patterns of a room temperature are set as shown by a chain line a' for cooling and as shown by a two-dot chain line b' for heating. These change patterns are set so that the temperature and humidity in the room at an air conditioning starting time t 1  may be higher than reference values when cooling and lower than reference values when heating, and the temperature and humidity in the room at an air conditioning ending time t 2  may be lower than reference values when cooling and higher than reference values when heating. At this time, the time-gradients and the fluctuation widths of temperature and humidity are determined within ranges which will not give uncomfortable feeling to residents. By so doing, values of temperature and humidity fall δ 1  and temperature and humidity rise δ 2  can be reduced.

Abstract: PROBLEM TO BE SOLVED: To drain sewage in the mixed state of solid foreign matters without requiring the installation of a screen in an inflow channel and the removing work of bitten solid foreign matters conducted while the operation of a pump is stopped. SOLUTION: Solid foreign matters mixed in sewage and sucked into a suction pipe 9 by the operation of a pump 3 are collected by the fixed tooth 10A of a solid foreign matter crushing means 10. The differential pressure between the pressure on the upstream side and the pressure on the downstream side of the solid foreign matter crushing means 10 is gradually increased as collection proceeds. When a set differential pressure between the reference differential pressure and an excessive differential pressure is detected by a differential pressure detecting means 13, the rotary tooth 10B of the solid foreign matter crushing means 10 is rotated by the output from a control means 14.  The solid foreign matters collected by the fixed tooth 10A are finely crushed by the cooperation of the rotary tooth 10B and fixed tooth 10A, and the sewage is drained by an impeller 4 in the mixed state of the solid foreign matters.

Abstract: PURPOSE:To simplify the constitution of the method by keeping the reduced intensity of magnetic fields generated on the traveling control guide lines provided to the traveling guide lines except its own one until an unmanned vehicle passes through an intersection after the vehicle reaches a point before the intersection. CONSTITUTION:The intensity of the magnetic field generated on a traveling control guide line 13 is detected by a magnetic field detection means 25 provided on an unmanned vehicle 20. Then the vehicle 20 is stopped when the detected magnetic field intensity is low. The vehicle 20 is started again when the magnetic field intensity is increased. Thus it is possible to evade such an inconvenient case where plural vehicles 20 enter an intersection at one time. As a result, plural communication equipments can be omitted together with a ground controller, a fixed point controller, and a special sensor. Then the constitution is simplified in a traveling control method for unmanned vehicles.
